Major Unit Assignment
Students will demonstrate their understanding of the nature of science by completing the steps of a scientific
experiment. Students will use the Sumter County Schools Experimental Design to answer a question or solve a problem
with a clear purpose for investigation.
Identify a question or problem.
Explain the purpose of investigating this question or problem.
Conduct background research on the topic, listing your findings in a bibliography.
Develop a testable hypothesis in an “If, then, because” statement.
Create a specific bulleted list of materials needed for the experiment.
Write out detailed procedures for how to do the experiment and how to analyze the data. Include any safety
Records all observations and data from the experiment in charts, graphs or tables.
Evaluate the results of the experiment.
Construct an argument using the evidence to explain if the results support or do not support the hypothesis and
write a conclusion statement.
Share the project in the school science fair or in the class.
